which like parts are similarly designated, Thelugs have registering ELPLGItlIIQSfQIfbOltS? Figure 1 represents aplan-View' of the ink- 18 by means ofjwhich the"fountain'-blades 2 mebhanismof =:P 2' P ess; showin are conn'ected therewiths Thumb=nuts:1-9 on the protruding end-portions of the bolts, are provided to clamp the blades in their adjusted positions.

The blades 20 which project laterally from the shaft fit at one of their ends loosely within the slots of the holders 1? and they are apertured to admit the bolts 18 by which they are held in place. The opposite ends of the blades are beveled and extend in close proximity to the fountain roller 6.

The blades extend into the ink contained in the fountain and by their reciprocating motion with the shaft on which they are mounted, they constantly stir and agitate the ink and thereby keep it at a uniform density throughoutthe length of the fountain and distribute it evenly over the surface of the fountain roller 6 throughout the length thereof. The blades 20 extend transversely of the upper portion of the fountain, lengthwise in a substantially. horizontal plane whereby to intersect the surface of a liquid in the fountaimthroughout the greaterportion of their lengths. Lint separated fromburlap or other fabrics that are being printed on the press, naturally lighton the surface of the liquid in the fountain and it is only by stirring the liquid at the surface, that this lint can be kept away from the rollers. For the same reason, theends of the blades are beveled, the bevels having a tendency to move the lint away from the roller that drips in the fountain.

The reciprocating motionof the shaft is effected through the medium of a curved drive-arm 21, the free end of which extends through the-spaceof the rollers 15 on the headofthe shaft.

' Fixed on the'gudgeons 22 and 23 at corresponding ends of the longitudinally reciprocating rollers 7 and 8, are spools 2% for the support of bearing boxes 25 provided with upwardly projecting studs 26. J The arm 21 is at a point between the gudgeons 22 and 23,- pivotally supported on a lug 27 extending from the main frame 28 of the printing press and it has at opposite sides of its pivot point, openings to admit thestuds 2,6 of the boxes 25.

I The pivotal connection of the arm with the lug is effected through the mediumof a pivotbolt 29 andthe studs, 26 are screw threaded at :their endsand providedwith nuts 30 to'hold thearm against upward motion.

, In the operation-of theinvention, an oscillaiting motion'is impartedto the drive-arm 21 by the reciprocating motion of the lens? and 8 alternately in opposite directions and the oscillating movement of the arm 21 is through the medium of the pivoted roller cage :13, con verted into a lengthwise reciprocating move- ;ment of the shaft 9 carrying the stirring- .blades20.

- The reciprocating motion of the blades through the :body of ink 31 contained in the 3' fountain 5,..stirs the ink thereby maintain;

ing it at a uniform density and evenly distributing it over the surface of the fountainroll 6, as hereinbefore explained.

The blade-holders are adjustable on the shaft. They can, therefore, be placed at different distances apart and their number may be varied, as best adapted to produce the desired result.

What we claim and desire to secure by Letters Patent is:

1. In inking mechanism for printing presses, an ink-fountain, a reciprocating inking roller, a stirring appliance for the fountain, and means for the operation of the appliance by the reciprocating movement of the roller.

2. In inking mechanism for printing presses, an ink-fountain, a reciprocating inking roller, a stirring appliance for the fountain, and a pivoted drive-arm connecting the appliance with the roller for its operation by the reciprocating movement thereof.

3. In inking mechanism for printing presses, an ink-fountain, a reciprocating inking roller, a reciprocating shaft, a blade on the shaft, within the fountain, and a pivoted drive arm'connecting the shaft with the roller for its operation by thereciprocating movement thereof.

"4c. In inking mechanism for printing presses, an ink-fountain, a reciprocating inking roller, a reciprocating shaft, a blade on the shaft, within the fountain, a pivoted roller cage on the shaft, rollers in the cage and a pivoted drive arm connected with the inking roller, and engaging with the rollers in th cage.

5. In inking mechanism for printing presses, an inkfountain, a fountain roller, a stirring appliance including a blade mounted .to move lengthwise of the ink fountain in a reciprocating motion, and mechanism to impart a reciprocating movement to the blade, the blade extending from a point in proximity to the roller, transversely of the upper portion of the fountain in a substantially horizontal plane wherebyto intersect the surface of a liquid in the fountain throughout the greater portion of its length.

6. In inking mechanism for printing presses,an ink fountain, a fountain roller, a stirring appliance including a blade mounted to move lengthwise of the ink fountain in a inking .mechanism for printing presses, an ink fountain, a reciprocating ink signatures.
